LaserWriter Pro 810: Set, Define, Change Usage

I am using the maintenance port on the LaserWriter Pro 810 to change some of the settings. However, when I issue the SET commands, power off the printer, then power it back on, the commands are not retained. Why?
When using the Remote Console Facility (RCF), there are three different commands you need to use; SET, DEFINE, and CHANGE.

SET
---
Temporary change. Commands entered using the SET command are lost when the printer reinitialized.

DEFINE
------
Permanent change, effective when the printer is reinitialized.

CHANGE
------
Permanent change, effective immediately.

In your example, the DEFINE or CHANGE command may be more appropriate if the change needs to be permanent.
